      X87: [wasm] Separate compilation from instantiation. · fe70bda4
      zhengxing.li authored 
        port c1d01aea (r37086)

  original commit message:
  Compilation of wasm functions happens before instantiation. Imports are linked afterwards, at instantiation time. Globals and memory are also
  allocated and then tied in via relocation at instantiation time.

  This paves the way for implementing Wasm.compile, a prerequisite to
  offering the compiled code serialization feature.

  Currently, the WasmModule::Compile method just returns a fixed array
  containing the code objects. More appropriate modeling of the compiled module to come.

  Opportunistically centralized the logic on how to update memory
  references, size, and globals, since that logic is the exact same on each
  architecture, except for the actual storing of values back in the
  instruction stream.

      [turbofan] Introduce simplified operator NumberAbs. · f50a601f
      bmeurer authored 
      Add NumberAbs operator to implement an inline version of Math.abs, that
can be optimized and eliminated. We don't use any speculation here, but
for now stick to the information we can infer (this way we avoid the
inherent deopt loops that Crankshaft has around Math.abs).

      X87: [builtins] Introduce proper Float64Cos and Float64Sin. · 3bc1a842
      zhengxing.li authored 
        port c781e831 (r37072)

  original commit message:
  Import base::ieee754::cos() and base::ieee754::sin() from fdlibm and
  introduce Float64Cos and Float64Sin TurboFan operator based on that,
  similar to what we do for Float64Log. Rewrite Math.cos() and Math.sin()
  as TurboFan builtins and use those operators to also inline Math.cos()
  and Math.sin() into optimized TurboFan functions.

Reason for revert:
Ready to test fix and reland.

> Reason for revert:
> Many build bots are failing with a message of the form:

>
> Can be relanded once we understand why these failures are occuring.
